Channel Scan Operation
This feature allows you to monitor all channels automatically
for valid signals. While scanning, you can transmit and receive.
When a signal is received, the scan is interrupted and will return
to scan mode 5 seconds after reception is terminated.
NOTE:
While the scan function is active,the MODE button will be inoperative.
The scan mode will reduce the overall battery life due
to the battery save function is overridden.
To enable the channel scan mode,
- From GMRS/FRS standby mode,momentarily press the power
Button; ( SCAN) will appear on the LCD display.
- The radio will display each channel (1-22) in order as the scan
mode operates to find an active main channel.
- When unit doesn't find any signals and you want to transmit,
press the PTT switch to return to home channel operation.
5 seconds after the communication is completed.
The transceiver will automatically resume scanning approximately

NOTES FOR GOOD COMMUNICATION
1.The GMRS120/120-2 22 channels are shared on a ‘take turns’ basis.
This means other groups may be talking on any of the channels.
A common code of ethics/courtesy is to switch to another vacant
channel and not to attempt to talk over someone who is already
using the channel you first selected.
2.The GMRS120/120-2 has been designed to maximize performance
and improve transmission range in the field. To avoid interference,
it is recommended that you do not use the units closer than
5 feet apart.
3.For best transmission results, always keep your mouth about
2-3 inches from the microphone (5) and speak slowly
in a normal voice.
4.To increase battery life, avoid features such as Scan.
These features will reduce operating time considerably.
Warning
• Do not operate the transceiver unless you are licensed to do so.
chemicals leaking from the batteries and corroding the transceiver.
Premature or accidental detonation may result.
• Remove the batteries from the transceiver if it is not expected to
be used for long periods. This will eliminate the possibility of
• Avoid exposing the transceiver to water or extremes of temperature.
• Do not use this device in or near a mining facility, which uses
remotely triggered explosives or in areas labeled “Blasting Area”.
• Do not attempt to modify or in any way increase the output of this
transceiver. Its output is designed to meet the legal limits set
by the FCC.
• Do not use this device or change its batteries in potentially
explosive atmospheres as sparks in such areas could result
in an explosion.
• Turn your transceiver off wherever posted notices restrict the use
of radios or cellular telephones. Facilities such as hospitals may
use equipment that is sensitive to RF energy.
